ᐅ Replace fixed plastic glazing panel with glass panel

Hello,
I recently moved into an apartment and have a fixed window panel in the conservatory that is currently filled with a plastic sheet.
I would like to replace this with a glass pane. However, I first need to remove the plastic element.

Here is my problem: Since I don’t know how the locking mechanism works, I have been unable to remove the panel.
Therefore, I’m asking for tips on how to replace the pane or how to open the trim.
I have already tried prying off the side strips, but they seem to extend behind the plastic sheet and don’t appear to be standard glazing beads that can simply be removed from the front.

I would appreciate any advice, including videos or search terms I could use. Unfortunately, I don’t know the window manufacturer, model, or the name of the locking mechanism.

Thank you in advance

Sorry, I was mistaken after all, and these are just standard glazing beads that I can simply remove.

These are actually the same glazing beads.

Since linking is not allowed here, try searching for "removing glazing beads" on Google. You will find useful videos and the right tools.

Addendum: I guess I was a bit slow...

Thank you. Unfortunately, another issue has come up. Unlike most other videos, I seem to have these blue locks. Does anyone know how to remove the glazing beads? Do I need to pay special attention to these locks?

I also have to use a lot of force to remove the glazing beads.
